A Double Decker is named as such because the bar has two layers – one is a cereal layer and the other is nougat before they are both covered by Cadbury milk chocolate. They layers are not exactly half and half with the nougat layer being 41% with the cereal being 9%.
It’s a popular bar because it offers both an unique flavour and texture in every bite – it’s both smooth and crunchy at once.
If you fancy a Double Decker because you’ve got some syns to burn then you’re in the right place as we’ll tell you how many syns are in each bar, how many syns per gram it holds and where in the chocolate bar syn league table it sits where it is compared with other popular UK chocolate bars. Let’s go!
Double Decker Syn Values
A Double Decker weighs 54.5 grams and contains 250 calories. This means a single Double Decker is worth 12.5 syns, has a syn per gram ratio of 0.23 and scores 90% in the chocolate bar table.
At 12.5 syns each it is amongst the biggest syn values for a single bar, comparable to a Twix, Dairy Milk Fruit & Nut and a Starbar. This is because it is quite heavy at 54 grams and is calorie dense. Many other bars worth lower syns are only lower because they are smaller.
Are Double Deckers worth the syns?
With a syn per gram ratio of 0.23, it is in the top 5 which is quite decent. This ratio signals that a Double Decker may be heavy but it is not crammed with sugar and fats – thanks in part to the light cereal and nougat. 0.23 syns per gram is similar to a Curly Wurly and a Crunchie.
Lastly, with a SynScore of 90% it is among to the best chocolate bars on our list, 0.23 syns per gram means it is an efficient use of syns and works your syn allowance much more than the vast majority of other chocolate bars. It is not healthy, but it is healthier than others on a gram to gram basis.
What does let it down from being crowned the king is its weight, if Cadbury made this bar 40g to reduce it’s single syn value it would be an excellent choice.
